The Process and Study of Sleep


             Restorative theory.
             Survival Theory.
             Restorative Theory.

             Replenish the stores of energy that have been depleted during the day.
             Allows damaged cells to be repaired.
             Detoxifies various muscles.
             During sleep our growth hormones increase which promote body repair and growth. Most people feel tired before they sleep and when they wake they feel more refreshed and energetic.
             However according to thus theory, those who are disabled would sleep less but this is not the case. There is also little evidence that we sleep more after an active day. .

             While sleeping an organism is not physically active with the environment and is less likely to attract attention of the potential predators. Animals with few natural predators ten to sleep longer (15 hours) as there is no danger. To grazing animals with many predators who only sleep 4 hours.
             This theory doesn't explain why sleep involves a loss of awareness as this places the organism at a greater risk.
